Application february 9, 1934, serial No. vlam n 1 claim. (Cl. ies-164) f This invention relates to a hinge designed to the hinge pins extending therethrough. Theend provide anabrupt throw-out for' an automobile door or other supported part.

It .is the general object of my invention to 5 provide a hinge of the defined typenn which the parts are simple indesign, economical tomanu-` facture and well adapted to theirdntended purl poses. i

My improved hinge is also so designed that .it

1o may be easily manufactured from sheet metal by pressing and bending operations.

My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed 'out 1B inthe appended claims.

A preferred form of the invention is shown in.l

the drawing, in which- Fig.' 1 is a plan view oi.' improved hinge in.

open position; v J 20 Fig. 2 is a sectional plan view o! the hinge in closed position;- n

3 is a side elevation of the open hinge, lool:--

ing in the direction of the arrow 3 in Fig. l

Figs. 4 and 5 are perspective views of two differg5 ent hinge links, and Fig. 6 is a ldetail sectional planview of parts .of the hinge in open position. Y

Referring to the drawing, my improved hinge comprises a hinge plate or leaf I0 to be secured so to an automobile body or pillar post or other stationary part, and a hinge plate or leaf II to be'! secured to a door or other swinging part. My improved hinge also comprises a relatively longer hinge link I2 anda shorter hinge link Il.-

I $5 'I'he hinge plate II) `is preferably made from ,an

single piece-of relatively heavy sheet metal and is provided with upper and lower out-tumed flanges 2li` and 2| having openings therein to receive hinge pins 22 and 23.A The axes of the hinge pins j 40 22 and 23 are parallel and ar'e preferably in a 4 5 lower outturned flanges 30 and 3| having bearing.

openings to receive hinge pins 32 and 33. The

axes of the pins 32 and 33 are parallel and are preferably disposed in a plane forming an acute angle with the surface of the hinge plate I I.

50 .The hinge links I2 and I4 are each preferablyv formed from a single piece of sheet metal, having end portions rolled to provide bearings forbearing portions of each linkare oiset from the 4body of the link, as clearlyshown in Fig. 2, and

' a sharp bend is provided at 35 inthe link I2 to increase the offset of the adjacent end bearing 5 which insures that the plates I 0 and vII will be 10 substantially parallel when in closed position vas shown in Fig. 2.

Theparts are assembled by placing the links I2 and) I4 between the end ilanges 20, 2|, 30 and 3i and by inserting hinge pins 22 and 32 through .15

the end bearings of the link I2, and hinge pins 23 and 33 through the end bearings oi.' the link I4.

Ilhe difference in length ofthe links and the ftiiilerence in spacing andangular position of the hinge pins causes the initial opening movement go of the hinge to be substantially a 'simple swinging movement about the axis of the hinge pin 23. J As soon; however, as the edge of the door clears the door jamb, the links I2 and Il come intoaction and provide an abrupt throw-cut motion by longbearings not eas ysubject to wear.

Having thus Jdesc bed my invention and the a5 advantages thereof. I do not wish'to be limited to the details herein disclosed, otherwise than 'as set forth in the claim. but what I claim is:

A sheet metal concealed door hinge comprising v four pivotally lconnected plates ofisubstantially 40 equal width, two of said platescomprisihg hinge leaves having means for attachment respivelyf to a support and to a swingably supported inem:A ber. the other two plates constituting links between said attachable leaves, a pair of integral 45 bearings at andformed from the opposite ends of each hinge link, ears at opposite edges of each of said attachable leaves arid overlapping said bearings,.and pivot pins extending through said bearings and said-ears.
